Update message in google chat from Jira - jira

Question

I am trying to create a notification in google chat whenever the status of a jira ticket changes. I have managed to sort the automation so that a message is sent to google chat every time the status changes but it creates a new thread each time. I would like to either update the original message with the new status or add a new message to the same thread.
I have the Automation configured to Send web request as follows has anyone managed to do this?
Webhook URL : https://chat.googleapis.com/v1/spaces/xxxx/messages?key=xxxx&token=xxxx
Header : Content-Type - application/json; charset=UTF-8
HTTP method : POST
Webhook body : Custom data
Custom data
"cards": [
{
"header": {
"title": "{{issue.key}}",
"subtitle": "{{issue.summary}}"
},
"sections": [
{
"widgets": [
{
"keyValue": {
"topLabel": "Reported by",
"content": "{{issue.reporter.displayName}}"
}
},
{
"keyValue": {
"topLabel": "Status",
"content": "{{issue.status.name}}"
}
}
]
},
{
"widgets": [
{
"buttons": [
{
"textButton": {
"text": "View Ticket",
"onClick": {
"openLink": {
"url": "{{issue.url.customer}}"
}
}
}
}
]
}
]
}
]
}
]
}
Example of what is happening

Answer 1

To create a new message under the same thread, you need to provide the thread as part of the message body
When you send the first message, the response contains a message resource that contains a thread resource
Include the thread name you obtain after sending the first message into the message body of the subsequent messages - this will enforce threading
To update an existing card, you need to follow the documentation:
Use the actionResponse.type UPDATE_MESSAGE instead of NEW_MESSAGE
I am not sure how you trigger an action response in your situation, but if you have a functionality that is able to trigger a new message, you can just as well trigger UPDATE_MESSAGE instead
